Several questions on the 816. I have a sony sc-dc173u camcorder that uses the mpeg4 format. I have no problem dragging a video into the video folder on the 816. It sees the file as a gom media file because I am using the gom media player. I click the file and gom opens the file and plays it.
When I unhook the 816 from the computer and look for the file in the video folder it is not there. I know there can be several reasons.

I am not using windows media player 11.. I cant , my copy of XP is not genuine. Do I have to use it? is there a replacement?

My format is not right, do I have to convert my video to a format that 816
can use?
